HI Snaken,
A debate on the format for the sprints is welcome but much of what you ask is already in place.
1. Please refer to the regs
http://www.cobracarclubnsw.org.au/us...uly%2010v1.pdf and you will see that groups are numbers not colours and for the friday practice there are 3 groups, Novice, intermediate and Advanced.
2. I think we have a good comprimise of 2 runs per session, this is a good balance of getting the cars thru and allowing a break for "tuning" and cooling. Wakefiled is shorter than Winton and 2 runs of 3 flying laps should not push cars over the edge.
Some numbers, 100 entrants= 12 groups of 8/9
12 groups x 4 runs = 48 runs
3 x flying laps 4.5 mins, time allowed to get overy one thru 8.75min per run.
It is quicker to run 2 runs per session as any delay waiting for cars to assemble in the dummy grid would jeopardise the 4 run format.
With over 100entrants it is the clubs intension to get thru 2 sessions of 2 runs of sprints on Sunday, typically only 3 were offered.
